This report describes a summative evaluation of Secrets of Circles, a 2,600 square foot exhibition created by Children's Discovery Museum of San Jose and funded by the National Science Foundation. The exhibition and related programs were designed to highlight the uses of circles and wheels in everyday life. Circles have properties that make them extremely effective as an engineering tool, and they are ubiquitous in cultures around the world. The appendix of this report inclues interview and observation protocols and questionnaires used in this study.

A series of interview studies was conducted to determine how museum visitors interpret scale ladders that focus on the nanoscale. These studies look at different versions of an example scale ladder in order to: a.) Iteratively develop a scale ladder that may be used by other informal science institutions. b.) Formulate guidelines to inform the design and use of other scale ladders. Interview questions used for studies 1-3 are included in the appendix of this report.
